Abstract. The present study investigates the propensity of predicting ore grindability characteristics and varying pulp densities through acoustic measurements on the Magotteaux ball mill. Specifically, the grinding behaviour of two different mill feeds (model quartz and iron ore) together with solid loadings (50, 57, and 67 wt% solids) were ...

Sound Transmitter for Ball Mill

Sound Transmitter for Ball Mill

Introduction. The Electronic Ear type PI 213 is a magnetic Sensor also known as Sound Transmitter, which is using the mill shell as a Membrane. This means the Sensor is only detecting the mill shell vibrations, caused by the Grinding balls hitting the mill lining and material in the mill, and so the Pyrotech Noise Level Sound Transmitter system ...

Then, lower force and torque pulses are exerted on the mill geometry and the noise level of torque decreases. ... There are two factors which make extremely difficult to correlate experimentally torque and filling level in a ball mill. One of them is a saturation effect appearing on torque as the mill filling increases. The other factor is the ...
